 I often see
 {{{
 if ( is_page(3) || is_page(8) || is_page(15) )
 }}}
 ... etc. in templates. Same goes for is_single(), is_author(),
 is_category() and perhaps is_tag(). It would be much cleaner/easier if
 these conditional tags can accept an array as argument as well. The
 attached patch changes the is_page() function to accept an array of page
 IDs, page slugs or page titles and can be used like this:

 {{{
 $my_pages = array ( 3, 'another-page', 'Special Page' );

 if ( is_page( $my_pages ) )
     $do_something...
 }}}

 It is (of course) backwards compatible and there's no noticeable
 performance hit at all, as is_page() is called just once instead of
 several times.
